Initial Set Up and Navigation
Speed Sensor Type and Cal
To automatically adjust the rate of applied products for vehicle speed, the field computer must be properly
calibrated for the sensor type providing speed information.
1.
Touch within the
Product Control
area at the bottom of the main screen.
2.
Touch within the
Miscellaneous
area on the CAN Controller Status screen.
3.
Select
Radar
or
Wheel
for the type of speed sensor connected to the Viper Pro.
Use the
Wheel
option if a magnetic type, such as a wheel or drive shaft magnet, system is used with the
Viper Pro. Set the speed sensor setting to the
Radar
option if a radar or GPS unit is sending speed
information to the Viper Pro.
4.
Touch the
Speed Cal
value and use the on-screen keypad to enter the new value.
Raven recommends the following speed calibration values for initial system setup.
These values are good starting points and generally yield adequate results, however, the speed cal should
be refined for each specific vehicle and speed sense system. See Appendix B,
, for instructions on refining the speed cal value.
Note:
The GPS speed over CANbus feature is only available with specific Raven speed sense nodes.
This feature utilizes NMEA speed over ground data transmitted over the CAN network which
eliminates the need for a separate, external speed sensor.
If another source will be used to detect vehicle speed, touch the
Calibration Assistance
button
and follow the on-screen instructions. Refer to Appendix B, Calculating the Calibration Values for
additional information about the calibration assistance procedure. The procedure outlined in Using
the Calibration Assistance section on page 226, should also be performed to refine or verify the
initial value used with a speed sensor not listed in the above table.

Touch
OK
to save the currently displayed settings and return to the CAN Controller Status screen.

NOTICE
When using the GPS speed over CANbus
feature, no refining or adjustment is necessary
or recommended to the speed cal value. Losing
GPS signal for more than a second will also
result in loss of the CAN speed signal which
may affect product application in progress.
